RAILROAD CROSSING.

Specification of Reissued Letters Patent. Reissued J 20 1922 Original No. 1,321,691, dated November 11, 1919,'Seria1 No. 303,028, filed June 10, 1919. Application for reissue filed August 11, 1921. Serial No. 491,572.

To all whom it may concern: V

Be it known that I, BYRON E. WILSON, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio, havev invented a new and useful Railroad Crossing, of which the following is a specification.

This invention is a cross-over device for intersecting'tracks of railways.

One of the objects of the invention is'zto provide a cross-over device of simple and economical construction by means of which cars may pass across the rails of either of the intersecting tracks without creating the jar, noise and clatter incident to, crossings now in general use. A'further object is to provide means whereby the intersection blocks of the cross-over device may be conveniently manipulated by operating devices located on the under side thereof so constructed to permit of the ready. disengagementof the parts for repairs and renewal.

without necessitating the raising of the base or otherwise disturbing the roadbed.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing Fig. 1 is a top plan view illustrating a cross-over device constructed in accordance with the invention. Figs. 2 and 3 are sectional views taken at right angles to each other on the lines 2-2 and 33 respectively, Fig. 1 illustrating the shiftable intersection blocks. Fig. 4 is adetail'view illustrating the connection between an intersection block and its actuating rodl.

Referring to the drawing, 10 designates a base provided with cross-over rails 11, and 12, intersecting each other at approximately right angles as shown in the drawing, although the angle may be varied. Each cross-over rail is provided with a groove for the flange of the car wheel, and at the points of intersection, said rails are provided with extensions 14. so disposed as to form angular recesses. Co-operating with the extensions 14 to'complete the recesses are rails having branches 15 and 16 connected by an angular portion, the branches 15 forming extensions of the rails 11 and the branches 16 formin extensions for the rails 12. Located within the recesses formed by the extensions 11 are intersection or crossover blocks 17, free to slide within the recesses, and provided on their undersides with cam receiving lugs 18 whlch. project downwardly through slots in the base lO. Each block is provided with onestra1ghtedge19 to bridge the space bet-w'eena rail '11. and abraneh 15, and a correspond ng edge 20 to bridge the space between :a rail 12 and a branch 16.

- The means illustrated for shifting the blocks consists of two bars 21, passed through and guided by suitable openings in the base 10, and each havingan offset ;portion 22 to provide a two edged cam portion wh1ch is engaged by a cam'receiving lug 18 of one ofthe blocks 17. The bars are gulded in their longitudinal movement in 'any suitabl'emanner, and maybe shifted in any desired way, the action being to shift the intersection blocks 17 so that one edge 19 or the other edge 20 of each block is selectively caused to aline itself with its rail 11 and branch 15 or its rail 12 and branch 16 as may be required. r s

The bars 21 are preferably shifted by a construction such as illustrated in Letters Patent 967 ,17 9 to J. Eymon, dated August 16th, 1910, consisting of a three armed lever 23 pivoted at- 2 1, and having twoof its arms slotted-to engage .pins on the bars. The third arm is connected by means of a rod 24: with a suitable operating device.

The construction above described is very similar to that disclosed in the patent to Eymon above referred to. The construction of said patent, while efiicient in operation. is open to the disadvantage that the operating bars cannot be disconnected from the intersection blocks without raising the base upon which the parts are mounted and otherwise disturbing the roadbcd. This objection is overcome in the present invent-ion by making the offset cam portion 22 of each operating bar 21 of substantially greater width than the main portion of the bar, and making the bar in two sections so connected at the points 25 (by nuts and bolts, for instance) as to permit the cam section to be readily separated from the other section. The Width of the opening in the cam lug 18 is much greater than the width of the bar 21 beyond either end of the cam portion 22. By reason of this arrangement, the bar may for ing-1th itsj intersectlngvbleck to permit the latter iexi gag is I actuat ng r l! be moved so as to entirely withdraw" the cam portion 22 from'the opening I in said i 1 lug,and becausefthe' portion of the beyond said openingis'much'narrower. than do the opening, ample clearance is provided to: permit that portion ofthebar to barn-awn str ight, through the lug 18, so that the block. -17; may "-be" raised" without disturbing the base on v the isurrounding" roaidbed-x "Havi g thus explained the nature invention and described an operative manner ofgoonstructing and u'sing the'zsame, although o without attempting to SGEFYfOIftl'l 2* all of i the terms: in whioh it may beln'ladey orfa'll of the; f0rms of its use what is claimed: ris
